SIRUP-PUMP FOR SODA-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 327,593, dated October 6, 1885.

Application filed September G, 1884. Serial Xo. 142,344. (No model.)

To @ZZ whom it may conce/'71,:

Be it known that I, AUGUSTUS E. Riou, a citizen of the United States, residing at Fall River, in the county of Bristol and State ot' Massachusetts, have invented a certain new and useful Improvement in Sirup-Pumps, ol' which the following, with th'c drawings accompanying and forming a part of this specification, is a full, clear, andexact description.

The object of my invention is to form a Sirup-pump more easily operated than those now in use, and to provide certain novel features for measuring or graduating the quantity of sirup to be used, and also arrange for its introduction into the bottle, with minor important details of construction hereinafter more fully described.

Figure l is a perspective elevation of the complete pump. Fig. 2 is a vertical sectional elevation, in which the valves and conduits are shown. Fig. 3 is a section showing attachment of cam and eccentric.

The pump herein shown and described is used in connection with suitable attachments for measuring and introducing into the interior of bottles sirup which constitutes a portion of the ingredients in various aerated drinks, which ingredients are forced into the bottles under considerable pressure.

Referring to the drawings, A is the barrel of the pump. B is an eccentric. (l is a rod connected with the eccentric strap or band L at one end, and with the plunger H at the other end, a being a connecting pin or carrier by which the rod C moves the plunger H up and down. c is a stuffing-box for the plunger; d, Aa cap upon the top of the barrel A. I) is an arm or crank provided with a suitable handle, by which motion is given to the eccentric, and through it communicated to the rod and plunger. The eccentric is secured to the pump by a pivot and nut, e.

Upon the lower end of plunger H is placed a compound valve, x', the exterior of which iills the interior of the barrel. This is made hollow, with orifices opening into the spaces in the barrel above the same, and represented by x4 x4. There is also fitted within this valve the stem m, carrying at its lower end the valve x, which has its seat on x5. Below this compound valve described is placed another valvi y, with its stem y. This is supported in it place by the spring .if-'

In the lower section of the pump is place a third valve, e, with its stem f', and whic is supported by the spring Thel lowe valve, with its parts, is protected by the cas K,which is screwed to the bottom ofthe pum]` In connection with the valve stem a stu or guide may be used, which pi'igccts throng] the side of case K, and lo which a screw-bolt, IL, is attached. Underneath the head ot' l1 is preferably placed a small collar or wheel adapted to revolve when pressed by the camstud oa when the eccentric is pressed down. The bolt hl may be attached lo stem and acl as the stud or guide, as shown.

The operation of the pump is follows: The sirup enters the pump-barrel at F and flows downward, filling the chamber above the compound valve. Upon the raising ot' the plunger H the sirup flows through the orifices x x4 and opens the valve x2, it being simply balanced in place by spring ad. Now, by moving the handle D downward the plunger is forced to descend, the valve of is closed and the valve y is opened aud the sirup is forced into the lower conduits of the pump. XVhen the plunger is down, the eccentric has carried the stud m so that it engages t the wheel i upon the bolt hf, and the lower valve, z, is opened, and the gas or air entering by the passage G closes the valve 'y and forces the sirnp out through E, where the pump is connected with the bottling-machine.

By this construction the valves are fully protected, and no part is exposed. It is impossible to have any of the sirup forced back into the upper chamber ofthe pump, and the quan tity entering the bott-lc connected with the bottling-machine is therefore uniform.

By the elnployment of the eccentric device I obtain at least double the power of the ordinary direct leverage andthe added advantage ofa full downward pressure ofthe arm. These points are important, as the strength required l to operate a pump of this character is considerable.

The eccentric strap or band L is secured in position upon the eccentric proper, B, by a :la-screw, f. Now, by placing a series of JreW-holes, g g g, in said band L, I provide ready means of accurately measuring the antity of sirup used, which quantity varies th the size of' bottle to be filled. For con- .nicnce I mark the holes gg f/ with the num- -er of ounces of sirup required. It is manilst that the change ol' the set-screw j' from K .ne hole to another must vary the length of `ic stroke of the plunger, and the quantity of :rup i'orced downward will be in exact-ratio i the distance the plunger carrying` the comound valve is raised in the body ofthe pump. lt will thus be seen that no error can pos- 'b'y he made in the proper quantity of sirup lo be used, and that such quantity will always be u nii'orm relatively to the size of bottles to be filled.

My invention may be used with a plunger having` a solid valve instead of the compound valve shown.

ln case it is not desired to introduce Sirup with the gas, my construction provides for introducing the latter without the former and Without actuating` the plunger.

By iemoving` the setsercw fthe canrstud can be operated in connection with the wheel. z' by simply turning the handle attached to the eccentric back and forth from the vertical line of the wheel t; or the valve z can be opened without removing the set-screwf, as the slight movement of the eccentric required to press the cani-stud m against wheel is insufficient to introduce sirup through the Valve x into the lower passages of the pump.

rlhe vcam-stud m is intended to press the wheel fi, immediately after the eccentric passes the center, downward. The opening of the valve z is regulated by the collar h on stern z', which is secured by a set-screw, as shown. i The collar is movable on the valve-stom. l

Having now described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination, in a Sirup-pump, of the body A, plunger II, provided with a compound Valve, x', the valve z, provided with the screw-bolt 7L, attached to its valve-stem, the valve '1, eccentric B, rod C, having the eccentric-strap L, with cam-stud m and lever D, all arranged and adapted to operate substantially as and for the purposes set forth.

2. In a siruppu'mp, the combination ofthe eccentric l, provided with the cam-stud fm, the eccentrioband L, and the rod C, adapted to operate the plunger H, the said canrstud m, adapted to operate the vulve z by means of the boit h, all substantially as and for the purposes Pet fcrt'r..

3. In a siruppump, the valve z, provided with the stem s', guide screw-bolt h, and Wheel f1?, and spring z', arranged to be operated substantially as and for the purposes specified.

4. In a Sirup-pump, the combination of the eccentric B, provided with the stud m and the crank D, and adapted to operate with the independent valve z, provided with the stern z and guide-bolt li.. substantially as and for the purposes set forth.

5. In a Sirup-pump, the independent valve z, in combination with a projection attached to the stem of said valve and a suitable eccentric provided with a cam, all adapted to operate substantially as and for the purposes set forth.
